CHARLES A. CARSCADIN, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO AMERICAN STEEL FOUNDRIES, OF CHICAGO ILLINOIS, A CORPORATION OF NEW JERSEY.

Application filed March 30,

To all whom it may concern Be it known that I, CHARLES A. CARS- CABIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Yokes for Draft-Gears, of which the following is a specification.

This invention relates to yokes for railway draft gears and has for its object the provision of a yoke having means to retain the drawbar butt and receive stresses therefrom without the aid of a key passing through the drawbar butt and constructed to permit insertion and removal of the drawbar butt without separating the yoke from the car frame.

A further object of my invention is the provision ofa yokehaving a separable and adjustable bottom member permitting interchangeable use of drawbar butts offdifferent sizes therewith.

Further objects and advantages of my invention reside in the various combinations hereinafter described and claimed as will be more apparent as the invention is better understood by reference to the following specification when read in connection with the accompanying drawing, illustrating the preferred embodiments thereof, in which- Figure 1 is a side elevation of a yoke according to my invention;

Referring to Figs. 1 and 3, inclusive, of the drawing 1 indicates a top member provided with a lug 2 at its forward end adapted to be engaged by a shoulder on the butt 3 of the drawbar 4:. The top member 1 is further provided with integral side walls 5 and 6 at each end thereof forming the ends of the yoke, the side walls 5 at the forward end being adapted to restrain lateral movements of the drawbar butt 3. In the form of my invention illustrated in Fig. 1 the side walls 6 at the rear end of the yoke are provided with a connecting web 7 at their lower ends. A bottom member 8 is provided at its forward end with an integral lug 9 adapted to be engaged by a shoulder on the butt 3 and which cooperates with the lug 2 on the top member to receive pulling stresses from the draw-bar 1. At its rearward end the bottom member 8 is provided with an integral lug 10 engaging the web 7 to hold the bottom member against forward movement when the structure is assembled and in use. A lug 11 on the upper side of the bottom member 8 bears against a follower plate (not shown).

The side walls '5 are provided with inwardly directed lugs 12 which limit downward movement of the bottom member 8 when released and obviously these lugs may be connected to form a continuous web if desired. A pin 13 is disposed through openings in the side walls 5 beneath the botton member 8 to hold the latter. in operative position as illustrated in Fig. 1. By removing the pin 13 the bottom member is permitted to drop sufiiciently to allow the butt 3 of the drawbar to pass between the lugs 2 and 9. The bottom member when released will rest upon the lugs 12 and may be raised into operative position and again secured by the pin 13 when the drawbar has been repaired or replaced. Any suitable means may be employed to secure the 'pin 13 in position.

Referring to Figs. 4, 5 and 6 of the drawing a top member 14 is provided at its forward end with a lug 15 and side walls 16 and 17 at its front and rear ends, respectively, as in the previously described form of my invention. The side walls 16 are connected by a web 18 while the side walls 17 are provided with openings to receive a pin 18 which is held in position by any suitable means. A bottom member l9 rests on the pin 18 and is provided at its forward endwith a lug -19 coeperating with'the lug 1 5 on the. top member .14 to receive pulling stresses from the drawbar. The bottom member 19 is provided beneath theL-lug-"1Q with a downwardly directed portion 20 which normallyrrests on the web 18'. Atits forward end the bottom member 19 is provided with laterally projectinglugs 21, engaging the rearedges of the side walls 17 to hold the bottom member 19 againstforward 'inovement'whe'nthe structure is assembled andin use. By withdrawing the pin 18 the rearend of the bottom member" 1.9 may be dropped sufliciently to'permit the? lugs '21 'to' clear the rear edgesof"-the"'side Walls 17 whereupontlie bottom member may f be moved forwardly until the downwardlyf projecting-portiori'20 clears the web 'l8. Thelug 19 is then spaced sufficiently from the" lug 15 to permit withdrawaliof' the drawbar which maybe again assembled" withf-tlie yoke by ja reversal of the operations described.

' My invention as hereinbefor'e "described may be embodied in tandem; as well as insingle spring yokes andI have illiistrate'd" in Figs. 7 ,Sand 9two forms of dividing walls'. j Referringqto 'Fig; 7 thetopfmember' is indicated at '22 and the bottommember at 23, the latter being provided mediallythere of with an upstanding'lu'g 24; The top member 22 is provided'withtwo depending integral plates 25' adapted to engage both. sides of the lug 24. JIn Figs. *8 and'9 the top and bottom members are indicated at 26 and-'27;respectively; The top member26 is provided witlr two depending integral plates 28',the lower ends of which engage recesses 29 in the bottom member 27. Either of the constructions described may" be em bodied in theyokes"ill1istrated' in F igs. 1 and 6 fto providetandem yokes, preserving all tl'ie advantages of my 'inventio'nas ap- 4'5 plied to single "springfyokesi Referring tofFigs 10 'and' 11 of the dr'aw-" mg, 30" and 31 indicate respectively the top 7 and bottom'members of 'the yoke provided at "their forwarden'ds with lugs 32 and 33" to receive pulling stresses'from the drawbar 3e. i Th eftop' member 30 providedwith side plates "35,36 "and 37 integral therewith at the front and i rear respectively and inter-" mediate theen dsf The si'de plates 35, 36 and I are provided withvertically spaced openings to receive "pins 38"which. supportthe bottom member 131 :in"operati ve position; The pins "38 "may be fprevented "from" acci-' dental withdrawal by any suitable means; By adjusting the" pins 38 in one or the other of" 'tlie"sets' 'of openings'the bottom member 31" may be fadj usted" relatively" to the "top member 30 "sothat drawbarshaving butts of different dimensionsmay be employed inter changeably with the" yoke!" The bottom member 31 is provided at-its rear end with laterally extending lugs 39 which engage the rear edges. of theiside-plates 36 and restrain the bottom member from forward movement under the drawbar stresses. Obviously the intermediate plates 37 may be omitted where a single spring yoke is de-" sired, the form of the yoke illustrated being designed for use-with double springs. The intermediate plates 37 may also be arranged asillustrated in Fig. 7 in which event the bottom member 31 would be supported by pins 38 at thefront and rear ends only of the'yoke. V v

From the'foregoing it will be readily un-. der'sto'o'd that I have perfected a yoke from which the butt of the drawbar may be readily Withdrawn when desired without removing the yoke from the car frame, it beingn'e'cessar'yonly to withdraw the fastening pins 'and drop the bottom member until the lug at the forwardend thereof clears the shoulder on'the' butt of the drawbar and permits the latter to drop suflicientlyt o'dis' engage the upper shoulder thereof from the lug at the forward end of the'top member. I have provided, moreover, a yoke with which drawbars having butts ofdiiferent dlignensions may be employedinterchange a 1y. v

It will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the" spirit "and scope of the invention or sacrificing-any of its-material advantages, 100 the forms hereinbefore' "described being merely preferred embodiments I thereof;

I claim V V 1.
